REAL SCIENCE: Magnetic Portals

Republibot 4.0's picture

A staple plot device of science fiction stories is the "wormhole," a spatio-temporal anomaly which permits faster-than-light travel between two points by bridging the gap between them via hyperspace or some supradimensional astral plane.

Apparently, they may not be entirely fictional. Elusive, mysterious, and transient, yes, but a NASA program is going to try to find what they call X-points or electron diffision regions which open up from time to time where the solar wind meets the Earth's magnetosphere.
